Answer:
<u>Heating water with an open flame</u>
<u>Explanation:</u>
Remember, we are told in the label that Acetone is a "flammable liquid and vapor." <em>Being flammable means the substance can easily be set on fire</em>, and we would expect an open flame from heating water to trigger an explosion (a disaster) in which the Acetone is set on fire causing life-threatening dangers to the second group of students.
To measure the kinetic engery from the inside and outside of something to be able to tell how hot or coll something is.. without touching it also
The answer is: the element is most likely to be a METALLOID
Answer:
The final volume of the sample of gas 
= 0.000151 
Explanation:
Initial volume 
= 200 ml = 0.0002
Initial temperature 
= 296 K
Initial pressure 
= 101.3 K pa
Final temperature 
= 336 K
Final pressure 
= K pa
Relation between P , V & T is given by
Put all the values in the above equation we get
= 0.000151
This is the final volume of the sample of gas.
Answer:
As temperature increases, the molecules and atoms move faster.
Explanation:
Molecules and atoms move according to how hot or cold the temperature is. As the temperature rises, the molecules and atoms will begin to move faster. As the temperature cools, the molecules and atoms will begin to move slower.
Hope this helps! :)
